What we are seeing is bigger than any particular campaign. What we are seeing is the political awakening of the "Upper Left." Think of the Left-Right spectrum as going from egalitarian to aristocratic; this puts Democrats to the Left and Republicans to the Right, as expected. Now, add a second dimension: freedom. Democratic Party represents the Lower Left – bigger government with the promise of more equality. The Republican Party has factions both in the Upper Right (Reagan, Forbes) and the Lower Right (the Bushes).
You'll have to go to The Free Liberal to see his chart.
A new political party which occupies the Upper Left has the potential to become as big or bigger than the existing major parties.
But there is no such party. But we do have Ron Paul. For the first time in ages, the Upper Left has an outlet other than apathy, bitterness or conspiracy theories.
Then he explains just how Paul fits in there.
